Scores are limited after uploading new song.

After uploading a new score It would show up on my profile twice, then the first song I had made would be blocked out and hidden from my profile with an error message telling me to upgrade. After trying to upload a new score It would say that I have too many scores on my profile (when I have four) I am afraid this would keep happening until I can't make any more scores. Is there anyone who had this same problem and/or can help me on this?
